A gardener has 100 feet of fencing in order to enclose a rectangular garden. The equation A(x)=x(50−x) gives the area of the garden whose width is x feet. What is a reasonable domain for this function? Explain.
Answer:
the answer is a
Step-by-step explanation:
A reasonable domain would be
−∞<x<∞
because
A(x)
is defined for all real numbers.

Step-by-step explanation:
Write an equation of a line in slope-intercept form that passes through the
given points. (2,-1) (6,3) *
Answer:
y = x - 3
Step-by-step explanation:
First, you need to find the slope from the two given points.
y2 - y1 / x2 - x1
= 3 - (-1) / 6 - 2
= 1
The slope is 1x or simply x.
For the y-intercept, you need to plug one of the coordinates into the equation, which is y = x + b
3 = 6 + b
-3 = b
So the equation is y = x - 3
To amend a country's constitution, 3/4
of the 46 states in that country must approve the amendment. If 35 states approve an amendment, will the constitution be amended?
Answer:
to answer the question we need to know if 35 out of 50 states is equal or greater than 3/4 if that is the case, the Constitution will be ammended, and that is represented like this:
35/50 >= 3/4
that inequality is saying that 35 states out of 50 is equal or greater than 3/4, lets simplify and modify the fractions to compare easily:
35/50 >= 3/4
7/10 >= 3/4
now we need to find the least common multiplier of 10 and 4 to take the fractions to a common denominator and compare easy. Lets multiply numerator and denominator for a correct number to get the fractions to denominator common 20, the lcm:
7/10 >= 3/4
(2/2)(7/10) >= (5/5)(3/4)
2*7/2*10 >= 5*3/5*4
14/20 >= 15/20
we can see that the inequality does not hold, so,
35/50 >= 3/4
does not hold either, therefore the Constitution cannot be ammended
Step-by-step explanation:
. For what value of x do the expressions 2x +2 and 3x – 6 have the same value?
Answer:
x = 8
Step-by-step explanation:
To find the solution, equate the 2 expressions, that is
3x - 6 = 2x + 2 ( subtract 2x from both sides )
x - 6 = 2 ( add 6 to both sides )
x = 8
As a check
2x + 2 = 2(8) + 2 = 16 + 2 = 18
3x - 6 = 3(8) - 6 = 24 - 6 = 18
Both expressions have the same value when x = 8

If 3 x/4 +2 =56.8, what is the value of x?
A) x≈ −2.891
B) x≈ 6.708
C) x≈ −4.323
D) x≈ −2.059
Answer:
the value of the x is 73.07
Step-by-step explanation:
The computation of the value of the x is shown below:
Given that
3x ÷ 4 + 2 = 56.8
3x + 8 ÷ 4 = 56.8
3x + 8 = 56.8 × 4
3x + 8 = 227.2
3x = 227.2 - 8
3x = 219.2
x = 73.07
Hence, the value of the x is 73.07

How many different 4-digit PIN codes are there that only include the digits 4, 5, 6, 7, 8 and 9
if each of those digits is only allowed to be used once?
Answer:
ecall that 6 + 6 + 6 = 6 × 3
Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.
Similarly,
6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42
Still by the same token,
2 + 2 + 2 + 2 = 2 × 4
In algebra, 2 × 4 can be written as (2)(4)
You can think of this as four groups of 2.
This situation is shown in the number line below.
You basically start at 0 and count by 2's until you have put four 2's on the number line. You end up at 8 and 8 is positive.

During a 40% off sale, Tessa pays $24 for a sled. What was the original price?
Answer:
$33.6
Step-by-step explanation:
24*1.4=33.6
the 1.4 represents the added 40% to find the original price of the sled
Answer:
original price = 40
Step-by-step explanation:
make an equation using the information given in the question, x will represent the original price
x - 0.4x = 24
or
x - 2/5x = 24
solve for x
x - 2/5x = 24
3/5x = 24
x = 40

Step-by-step explanation:
A beachball has a radius of 10 inches. Find the volume of the beachball, in cubic inches.
Round your answer to the nearest whole number.
Answer:
4189 cubic inches
Step-by-step explanation:
Use the formula for the volume of a sphere: V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Plug in the radius as r, and simplify:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](10³)
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](1000)
V = 4188.79
Round to the nearest whole number
= 4189
So, the volume of the beachball is 4189 cubic inches
Melody Pond and a tree cast a shadow at the same time of day. Melody is 5.6 feet tall and casts a 10-foot shadow. If the length of the tree's shadow is 62 feet, what is the height of the tree?
Answer:
34.72 feets
Step-by-step explanation:
Using the relation :
Length of tree / shadow of tree = height of melody / shadow of melody
From the details given in the question :
Let height of tree = h
h / 62 = 5.6 / 10
Cross multiply
h * 10 = 62 * 5.6
h = 347.2 / 10
h = 34.72 feets
Hence, the height of tree is 34.72 feets

Heather Johnson bought a new set of tires for $436.00 and a car seat for $22.85. The state tax rate is 6%, the county tax rate is 1.5%, and the city tax rate is 0.5%. What is the total purchase price?
Answer:
$495.56
Step-by-step explanation:
Tax increases the price paid for a good or service. So, the total price paid for the goods would increase by the total amount of tax
Sum of the three taxes = 6% + 1.5% + 0.5% = 8%
Total cost of items purchased = $436 + $22.85 = $485.85
Total purchase price = Total cost of items purchased x (1 + total tax)
$485.85 x (1.08) = $495.56

Major arc CBD measures 300 degrees. Which is the radian measure of its corresponding central angle? O 4 pie/3 O 5 pie/6 O 5 pie/3 O 11 pie/6
Answer:
[tex]\dfrac{5\pi}{3}[/tex]
Step-by-step explanation:
Given that,
Major arc CBD measures 300 degrees.
We need to find the radian measure of its corresponding central angle.
Radian measure is given by :
[tex]R=\dfrac{\pi}{180}\times d\\\\R=\dfrac{\pi}{180}\times 300\\\\R=\dfrac{5\pi}{3}[/tex]
So, the radian measure is [tex]\dfrac{5\pi}{3}[/tex].

The equation h = -16t 2+ 53x + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked. What is the maximum height the football reaches?
Answer: The maximum height the football reaches = 51.89 feet.
Step-by-step explanation:
Given: The equation [tex]h = -16t^2+ 53t + 8[/tex] gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.
Differentiate the given equation, we get
[tex]h'=-(2)16t+53=-32t+53[/tex] (i)
Put [tex]h'=0[/tex]
[tex]\Rightarrow\ -32t+53=0\\\\\Rightarrow\ t=\dfrac{53}{32}\approx1.65625[/tex]
Differentiate (i) w.r.t. t, we get
[tex]h''=-32[/tex] < 0 i.e. h is maximum at t= 1.65625
The value of h at t= 1.65625 will be [tex]-16(1.65625)^2+53(1.65625)+8=51.890625\approx51.89\text{ feet}[/tex]
Hence, the maximum height the football reaches = 51.89 feet.
